Based on the answers provided, the following corrections need to be made to the 3D object:

1. Modify the object to resemble a thermometer. This typically involves an elongated, narrow shape with a temperature scale. 

2. Ensure the rectangle attached to the circle has its height about 7 times its width. This is currently unclear and needs to be confirmed.

3. Add a small circular hole near the top edge of the rectangle. Currently, there is no hole and the rectangle appears solid throughout.
